Assessment of Subclinical Psychotic Symptoms in Patients with Rheumatoid Arthritis and Spondyloarthritis.

Inflammatory and autoimmune processes have been associated with the onset of depressive and psychotic symptoms. Rheumatoid arthritis (RA) and spondyloarthritis (SpA) are rheumatic diseases with an inflammatory etiology. A high prevalence of depressive and anxiety-related comorbidity has been reported for both diseases, with no evidence of a greater prevalence of psychosis.

Validation of the Spanish-language Cardiff Anomalous Perception Scale.

The Cardiff Anomalous Perceptions Scale (CAPS) is a psychometric measure of hallucinatory experience. It has been widely used in English and used in initial studies in Spanish but a full validation study has not yet been published. We report a validation study of the Spanish-language CAPS, conducted in both Spain and Colombia to cover both European and Latin American Spanish.

Depersonalisation and schizophrenia: Comparative study of initial and multiple episodes of schizophrenia.

Introduction: The phenomena of depersonalisation/derealisation have classically been associated with the initial phases of psychosis, and it is assumed that they would precede (even by years) the onset of clinical psychosis, being much more common in the prodromal and acute phases of the illness. The aims of the present study are to analyse the differences in depersonalisation/derealisation between patients with initial and multiple episodes and the factors that could influence this.

Material And Methods: A descriptive, controlled and cross-sectional study of 48 patients diagnosed with paranoid schizophrenia (20 with an initial episode and 28 with multiple episodes).

[Factorial Structure of the Cardiff Anomalous Perceptions Scale (CAPS) in a Colombian Population Sample].

Background: The continuum hypothesis of psychosis assumes that hallucinations are not exclusive of psychotic disorders. A number of psychometric tests have been developed to assess psychosis using a dimensional model.

Objectives: To determine the factorial structure of the Cardiff Anomalous Perceptions Scale (CAPS) for the Colombian population, and to contrast the fit of two factor models previously reported in the literature by conducting a confirmatory factor analysis (CFA).

[Validation of the Spanish version of the Cardiff Anomalous Perceptions Scale in the general population].

Introduction: Interest in the existence of anomalous perceptions in the general population has increased greatly over recent years. Because of this, it has been possible to extend the knowledge regarding the theory of psychosis as a dimensional model. This study has aimed to validate the Spanish version of the Cardiff Anomalous Perceptions Scale (CAPS) the general population.
